GEABING FOR HORSE-GBOOMERS.

Specification of Letters Patent.

Patented Jan. 31, 1911.

Application filed February 24, 1810. Serial No. 645,886.

To all whom it may concern:

Be it known that I, Gnonon F. Pmsss, citizen of the United States,'residing at Spokane, in the county of Spokane and State of Washington, have invented certain new and useful Improvements in Gearing for Horse-Groomers, of which the following is a specification.

This invention comprehends certain new and useful improvements in gearing and relates particularly 'to an improved arrangement of gearing designed for use in the o eration of grooming horses, although it is to be understood that the invention is applicable for use generally wherever it is desired to impart motion from a driving shaft to a driven shaft and tozsecure by a quick movement the reverse rotation of the that driven shaft, While the drive shaft rotates continuously in one direction, the device being applicable for use in connection with dental engines, reamin and boring tools, and the like, as Well as or the use for which it is primarily designed as .above set forth.

The invention has for its primary object a simple durable and efiicient construction of device of this character which is composed of comparatively few parts which may be cheaply manufactured and readily assembled, the parts being so arranged that a quick reverse of the driven shaft may be made without affecting the continuous rotation of the drive shaft in one direction, this being particularly advantageous in horse grooming apparatus so that in ass ing from-one portion of the horses hi e to another, the direction of rotation of the brush may be changed whenever desired ac-' cording to the direction in which the hair lies. And another object of the invention is a device of this type, the parts of which are so correlated with each other that the operator may reverse the movement of the driven shaft by manipulating the device with the thumb or finger of the same hand raspsvthe handle, the adjustment of the evice being capable of being performed entirely by one hand, thereb leaving the other hand of the operator ree.

With these and other objects in view as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and claim. For a full understanding of the invention,

reference is to be had to the following descrlption and accompanying drawings, in which: Figure 1 is a perspective view of one form or embodiment of m invention; Fig. 2 is an elevation of the mterior of the casing, one half thereof being removed and some parts being shown in section and others in dotted lines; Fig. 3 is a transverse sectional view of the device on the line 33 of Fi 2, lookin in the direction of the arrows; Fig. a is a similar view on the line 4-4 of Fi 2, looking in the direction of the arrows; ig. 5 is a side elevation of the gear casing, a part being broken out and in section; and, ig. 6 is a detail perspective view of a portion of the driven shaft and the double clutch member adapted to be mounted thereon.

Corresponding and like parts are referred to in the followin description and indicated in all the views 0 the drawings by the same reference characters.

As is customary in this class of devices, a

handle 1 is provided whereby the device may be freely held by one hand of the operator, and a drive shaft 2 is mounted in sand handle and receives a continuous rotary movement in one direction, as through the instrumenta-lity of a flexible shaft, a portion of which is indicated at 3 in Fig. 1. The handle embodies a bushing 4 which is screwed into a boss 5 formed on a two-part casing 6, the two parts or halves of the easing being complemental and being adapted to be secured together in any desired way. The wooden cessed, as indicated at 7, to receive the twopart bushing 5- of the casing. The shaft 2 extends through the casing from end to end,

12 also carries a loose gear wheel 14 which meshes with an idler pinion 15 and the latter in turn meshes with the spur pinion 10 before mentioned. Between the gear wheels 11 and 14 a double clutch member 16 is mounted, said clutch member being designed portion 1 of the handle is redie-1 and is provided with a finger or thumb .to' alternately engage the: clutch faces of the gearv wheels, as indicated best in Fig;

.2. The clutch member 16-has a spline connection with a collar or sleeve 17 fast on'the 5i shaft 12, and the said clutch member is operated b means of a yoke: 18 which is provided wlthrollers 19 mounted in the groove 20 of the clutch member,said yoke beln se-' cured to and movable with astub sha or s indle 21 'ournaled in the casing, as best. ilustrated m Fig. 4. The spindle 21 projects outside of the casing, as shown, and to ts outer projectingend a shipperlever 22 is connected at one end. The opposite end of said shipper lever extends along the hanpiece 23, wherebyiit may. be easily manipulated bythe same hand of the operator which grasps the handle 1. The shipper lever 22' is. provided intermediate of its ends with a hollow boss. 24 in which a spring pressed detent 25 is mounted, said detent being designed to snap in any one of three-sockets 26 which are formed .in the exterior walls of the boss 27 in which the'spindle 21 is mounted, whereby to prevent the accidental movement of they shipper lever after it has been adjusted to the desiredposition,

From the foregoing descriptionin cbn-' nection with the accompanying drawings, the operation of my. improved gearing will be apparent.

In the practical use of the device,'the gear wheels 11 and 14 will be'continuously rotatedin opposite directions, while the drive shaft 2 will be continuously operated in one direction. If it be desired to turn the shaft v12 in a direction opposite tothat in which the shaft 2 is located, the operator, graspingthe handle 1 with his right hand, will use his thumb or finger against the thumb piece 23 to swing the shipper lever 22 over to the left and will thereby carry the clutch member 16 into engagement with the gear wheel 11, so as to secure the gear wheel 11 to the shaft 12. If it be desired to turn the shaft 12 in the same directionas the drive shaft 2, the shipper lever will'be swung over to the right so as to eflect the engagement of the clutch 16 with the gear. wheel 14, and in order to stop the rotation of the shaft 12 without affecting the continuous rotation of the drive shaft 2, it is only necessary to bring the shipper lever to a middle position,- whereupon the clutch will be directed to a neutral position between the two gear wheels comprising a casing, a handle connectedv 11 and 13,. permitting them both to run free in opposite directions as the shaft 2 is rotated.

I Having thus described. the invention, what is claimed as new is:

1. A gearing of the character described,
